Battery Deka or Duracell
I have had excellent results from a Deka Intimidator 9A48 High Performance AGM Battery Deka / Remy part # 9AGM48 installed Dec 2010
Pros: excellent results
Part number: 9AGM48
I don't recommend anything less than the DEKA ETX-20L for a car that see true street duties. The ETX-14 is 200 CCA @ 12 lbs, and the 4 lbs weight loss isn't worth it for 70 CCA loss on a small battery in charge of starting a car. The ETX-18L does 270 CCA @ 16 lbs and much more suitable for our 4 banger application. The ETX-18 however is the one I recommend to 95% of readers of this thread. It cranks out 300 CCA at 18 lbs, which is still plenty light.
Pros: cranks out 300 CCA
Cons: 70 CCA loss
I've always had sucess with the Deka ETX-20L in the DSMs, two EVOs, a Saturn race car, and now the TT (most of them running on E85 which is hard to start on cold winter mornings). As long as you discipline yourself to not run accessories with the engine off, they are a great option!
Pros: great option, sucess with Deka
Cons: discipline yourself
Vehicle:
Audi TT
Part number: ETX-20L
I had an Optima 5 or 6 years ago but I heard the quality has went down and the warranty isn't as good as it used to be. I picked up a Deka intimidator deep cycle battery and It's by far the best battery I've owned.
Pros: best battery I've owned
Cons: quality has went down
I got a deka 15 and i love it
Pros: i love it
Part number: 15
I'm running a Deka ETX 14 and us a battery tender jr. works great
Pros: works great
I had the ETX14 in my N/A R32 for over 2 years and only time it really drains down is short starts and stops from the afterrun coolant pumps running for 5 minutes.
Pros: lasted over 2 years
Cons: drains with short stops
Vehicle:
Volkswagen
I have the DEKA ETX20L it started my car in 15 degree weather... I leave the car off for 3 days out of the week and it starts right up... I've been using it daily for quite a while... it has died on me a few times but it was my fault for leaving the fan on.. I just recharged it and it has been fine.
Pros: starts right up
Cons: died a few times
just had a etx14 sat in car for over a month and started right up.
Pros: started right up
So ever since I put subwoofers in my car they seem to be killing my batteries. My original battery lasted about 2 years (car was barely used for these 2 years), battery after that lasted a year (replaced last summer), and now it seems as if my current battery is going. I wanted to grab food before going to work yesterday so I got some food at Mcdonalds and sat in my car for 20-30 mins eating and listening to music. I went to fill my car up with gas after work (gas station not even a mile away) and the car barely started, normally it turns over very quickly, you could tell the car was REALLY struggling due to battery (everything dimmed as well). This was at night so my headlights were on while I was filling up. At the beginning of summer I went to a drive-in and was able to watch an entire movie without my battery dying. The battery is a Duracell with 725 CCA and 890 CA @ 32F
Pros: watched movie without dying
Cons: short lifespan, struggles to start, dims lights
